Rockies hang on to avoid a sweep

Jorge De La Rosa pitched eight scoreless innings to win his sixth straight start against San Francisco and help the Colorado Rockies avoid a three-game sweep against the Giants with a 4-3 victory Wednesday night.

The Giants had the tying run at third in the ninth, but Rafael Betancourt struck out Nate Schierholtz.

Ian Stewart and Troy Tulowitzki homered for the Rockies, who had lost four straight, including the first two in this series. But with De La Rosa’s outpitching All-Star Matt Cain (13-6) and once again dominating the Giants, Colorado leaves town with a 3 1/2 -game lead over San Francisco.
